METHOD FOR CREATING OF LONG-DURATION AUTUMN-WINTER PASTURE ECOSYSTEMS

摘要

FIELD: agriculture, in particular, growing of farm crops adapted for feeding of animals.;SUBSTANCE: method involves sowing seeds of annual and perennial fodder crops in parallel alternating rows, said crops being similar in cultivation methods and differing in nutritive substance content; after sowing, providing cultivation of spacings at initial stage of growing and life of plants for eliminating weed plants lacking feeding qualities; harvesting mixtures along rows by mowing for producing of hey or by grazing of crops; forming pasture ecosystems from feed shrubs, subshrubs and perennial grasses used in the ratio of 20-30%, 65-75% and 3-8%, respectively. Method allows autumn-winter pastures to be provided with stable plant associations having increased productivity. In the regions where total annual precipitation is 170-250 mm, yield of dry fodder mass from pastures is 1.0-1.2 t/hectare, and in the regions where total annual precipitation is 260-450 mm, yield of dry fodder mass is 1.5-2.0 t/hectare.;EFFECT: increased stability and productivity of fodder crop phytocenosis in long-duration pasture ecosystems.;3 tbl
